An Investigation Gone Wrong (Lukas x F. Reader)

As (Y/N) walked through her school's hallways, she pulled her phone out from her pocket. She had been waiting for a little while for her friend to arrive at school. (F/N) was running late as per the usual. (Y/N) walked over to her locker and started to undo the combination lock on it. When she managed to undo it, she started to rummage through for her chemistry book since that was her first period class.

While she was rummaging through her locker, (F/N) came running up to her. (F/N) doubled over while panting heavily. (Y/N) gave her friend a confused look before shutting her locker and turning to face them.

"Where have you been, (F/N)?" (Y/N) asked.

(F/N) caught their breath and stood up straight, "My folks were still asleep when I had to go so I ran all the way here."

(Y/N) rolled her eyes, nudging her friend's side playfully. The class bell rang which meant they had five more minutes to get to class. (Y/N) chuckled as she watched her friend frantically look through their locker for their algebra book. Once her friend found it, the two of them rushed off to their classes.

During class, (Y/N) asked her teacher to use the restroom. The teacher nodded, motioning to the hall passes next to his desk. (Y/N) made her way up to the desk and grabbed a pass before heading out of the classroom. She quickly made her way to the bathroom, not wanting to waste much class time. Even though (Y/N) was already done with her assignment, she liked to use her free time to work on homework. So, she didn't want to waste too much time in the bathroom.

When (Y/N) was in the bathroom, she heard a familiar scream coming from outside the bathroom. She immediately froze up, not knowing what to do. The bathroom she had to use was all the way on the other side of the school where there were no teachers. (Y/N) sat there for a couple minutes in fear from what she had heard. Once she was able to, (Y/N) finished up before washing her hands and leaving the bathroom.

As she exited the bathroom, she noticed a trail of blood outside of the door. Curious of what it led to, (Y/N) started to follow the trail. When she reached the end of the trail, her eyes widened at what she saw. In front of her was a young man with blonde hair stabbing (F/N)'s lifeless body. (Y/N) let out a gasp, causing the male to look up at her. He chuckled as he got up onto his feet, his bloody knife in hand. He started to make his way towards her with a mischievous grin.

"What do we have here? A little girl playing detective?" he said huskily.

(Y/N) gulped as she shakily backed away, "Y-You killed them... You killed my friend!"

"Well, well, someone's got a little head on her shoulders~" he chuckled.

(Y/N) yelped as her back hit the cold plaster wall of the school building. The blonde male chuckled before towering himself over (Y/N).

"I'm sorry cutie, but I can't afford any witnesses..." he said.

Before (Y/N) could utter another word or even scream, the male took a cloth out of his pocket and placed it up to her mouth. Her muffled cries for help slowly died down as she breathed in the sedation chemicals. Soon enough, (Y/N)'s body became limp in the male's arms. The young man chuckled as he started to carry her out of the school.

After a couple hours, (Y/N) finally started to regain consciousness. Her eyes fluttered open, revealing that she was tied to a chair. Her wrists and ankles were duct taped together while her torso was fastened to the chair with a rope.

"Mph!" she tried to yell, but her mouth was gagged with a piece of cloth.

(Y/N) gulped as she heard a faint chuckle coming from the shadows. She heard a door slam shut before the sound of footsteps coming downstairs rang through the cold, dim room. (Y/N) looked up, her eyes widening when she saw the familiar blonde from earlier. She hadn't had a good look at him, but she now was able to see him fully.

The man in front of her was Lukas. (Y/N) had been warned by many people in her school about it. He was known as the school's yandere. Everyone knew not to mess with him, because he was a known psychopath. He was wanted by the state police, so she was shocked he hadn't been caught yet. She snapped out of her train of thought when she felt something cold on her neck. She noticed that Lukas was inches away from her face, her eyes falling to the blade touching her neck.

"What's the matter? Never seen a knife before?" Lukas asked teasingly.

(Y/N) gulped a bit, causing her captor to chuckle. He pulled the knife away from her neck, but still held it in his hand. He took his other hand and ripped the cloth out of her mouth. (Y/N) gasped for air as Lukas chuckled at her.

"How dare you kill (F/N)?! What did they do to you?!" she shouted, glaring at Lukas coldly.

Lukas stopped chuckling and formed a stern look, "(F/N) was in the way, so they needed to go!"

"In the way of WHAT EXACTLY?!" (Y/N) asked furiously.

Lukas smirked, leaning in close to her ear before whispering, "In the way of you my darling~"

(Y/N) scowled, "You better leave me the hell alone you-YOU PSYCHOPATH!"

Lukas chuckled once again, "I will, on one condition~"

"Bring it on! I could care less at this point!" I practically screamed at him.

Lukas grabbed her chin, "Keep your mouth shut about what you saw! That's my only request~"

"Deal, just leave me alone you creep!" I exclaimed.

Lukas let go of her and smirked, "Alright, we have a deal then~"

(Y/N) let out a relieved sigh as Lukas started to undo her restraints. But before he untied the rope, Lukas looked up at (Y/N).

"Oh, one more thing~" he said huskily.

(Y/N) sighed and rolled her eyes at him, "What is it now?"

"I want you to be mine~ And only mine~" Lukas responded.

The young woman gulped, "F-Fine! If it means you'll leave me alone and not kill again, then yes!"

Lukas smirked, "Good girl~"

(Y/N) sighed in relief as Lukas finished releasing her from her bondage. Once the rope around her torso fell to the ground, Lukas took a hold of her wrists before pulling her out of the chair. (Y/N) went to say something but right as she opened her mouth, Lukas pulled her close and kissed her. (Y/N) froze in shock but slowly melted in.

At first, (Y/N) felt uncomfortable in the kiss. But after a couple moments, a warm, passionate feeling filled the air around them. She felt her cheek heating up a bit, meaning she was blushing.

Once the pair grew tired of kissing, they pulled away from each other. Lukas smiled and chuckled at the shocked look on (Y/N)'s face. He let go of her and took a couple steps back.

"Better get used to that happening more often, cutie~" Lukas chuckled.

(Y/N) cleared her throat and stuttered, "I-I guess I'll h-h-have to..."

Lukas patted her back before motioning her to the door. He led (Y/N) out of the house, allowing her to walk freely back home. He knew she wouldn't break their deal because she'd already seen what would happen if she did...
